To all whom it may concern: I

Be it known that I, THOMAS O. SOHRADER, a citizen of the United States, Allentown, in the county of Lehigh and State of Pennsylvania, have invented certainnew and useful Improvements in of which the following y invention has relation to a latch for closing refrigerator doors among other types of doors; and in such connection it relates to the particular onstructive arrangement of the same. I

The principal objects of my invention are first, to provide a latch with a bolt andan operating lever-handle to latch the door in either the raised or lowered position of the handle by manual pressure exerted against thereby cause the provide a latch in which the coiled spring thereof in the compressed condit'on of the same firmly holds the bolt of the latch so that by pressure exerted manually against the door will automatically lock the arranged with the keeper. to thus seeurel door; and third, to provide a late so; that the coiled spring thereof in of the spring becoming disarranged or en, the operatin ley'er-handle of the or engage the late boltfrom or with the keeper tothus instantly open or close the door.

The nature and scope as well as characteristic'fe'atures of my invention will be more fully understood tlon takenin connection with the accomfront elevational view of a emb tures of my invention.

. Having described the nature and objects of my invention, what I claim as new and desire to secure by Letters Patent is z- 1. The combination, in a latch, of a keeper and a cam having a bolt formed therewlth and engaging said keeper, a cross-pin, a rod mounted on said. pin

pivotally connected with said pin and a link connected with said handle and cam opposite the position of thebolt of said cam, substantially as and for the purposes described. i

2. The combination in a latch, of a keeper and a cam having a bolt arranged to engage said keeper, a cross-pin, a rod '-slidably mounted onsaid pin and connected with said cam, a spring mounted on said rod, the terminals whereof respectively, said pin and cam, an operating lever-handle pivotally connected with said pin and a link connected with said handle and cam opposite the position of the bolt of said cam, substantially as and for the purposes described. a 1
